Roughly 15% of our greenhouse gas emissions come from buildings. Carbon emissions leak from concrete and are a byproduct of steel production. Fortunately some very smart people are looking to solve this problem and we've gathered them to talk about the present and future of climate-friendly building materials. We are joined by Massachusetts State Senator Cynthia Creem; Eric Dunford, Senior Director of Government Affairs at CarbonCure; Adam Rauwerdink, Senior VP for Business Development at Boston Metal; Christopher Neidl, Co-Founder of the OpenAir Collective; and Rebecca Esau, Manager for Carbon-Free Buildings at the Rocky Mountain Institute.
